or "brush-rods, between said rotary teazels.

in such a manner that every rotary teazel, or a plurality of such teazels, is vor are followed b. a teazel-rod, .or by a brush-rod. The 'ob -ect of such interposition being, to range and toteazel the nap raised by said rotary teazels. Besides this raising-gigs are knoWn,--vv-herein rotary teazels, or teazelrods, are arranged to execute lateral movements, i. e in the direction of their ax s. The teeth of-the card-clothing of such totary-teazels, or of such teazel-rods, are d1- rected sidewise, vso thatithe pointsof said teeth execute a; transverse teazelingaction upon the warp-threads on account of the axial movements of said teazeleorgans. It 1s said rotary teazels, or of said teazel-rods,

produce a raising-gigfor simultaneously to unknown teazeling-process. To assure the evident that for reasons of the combined motions of the cloth on the one hand, and of on the other hand, the teeth of these tea zelorgans cannot strike the Warp-threads at right angles but underan acute angle only.

The object of my present invention is to performing the longitudinal as Well as the transverse or cross teazeling. To this endfI combine in the same tea'zel drum fixed rotary .teazels and reciprocating teazel-devices insuch a manner, as to obtain a new, hitherlatter, the reciprocating teazehdeyices are gnade toact upon the arp-threads only,

exert their influence not only upon the Weft- V ,threadsgb'ut also upon the Warp-threads, as

, In thefra-me 1 is journaled the drivingshaft 2 of a teazel-drum,.-3 composed ofprotary teazels a ,and of reciprocating teazeldevices j The latter are in this instance of cylindrical shape and can execute rotary as wellas reciprocating movements. The rotary teazels i and said teazel-devices :5 are journaled in the drum-heads 6 and 57 (Fig. 1). To rotate the iixed rotary teazels '4:

with agreater circumferential velocity than I the rotatable reciprocating teaZel-devices .5, each rotary teazelis provided with a pinion 8 that meshes With a Wheel-rim 9 attached to a spur-Wheel 10 which cooperates with the larger pinions 11 of said teazel-devices 5.

These pinions 11 are slidin-gly seated upon the-shaft22 of said teazel-devices by means of a feather-hey andrareheld againstiaxial 'il isphicornentpby their hu los, as indicated in 1 g. V v

The Wheel 10 is provided With :ajsleeved hub 19, which freely rotates upon sthe driving-shaft 2 and carries a- :step-pulley. 13to vary the circumferential speed of the active members 4 ands-5 of the teazel-drum'3, .if

deemed necessary. The teazel-devices 5 .are preferably arranged v in two groups to simplijfy their v ,reciprocation. To .compulsori-ly produce thelatter I employ a doublee'ccen,

tric 14: the sheaves ofwhichare set at .an-

gle :of 180 to each other andconnected with a spur-Wheel 15 revolubly mounted upon the; driving -zshaft rsaid spur wheel meshes'with a pinion 16 secured to a shaft 17,

centric-strap 19 four links 20 are attached, the free .ends of Whichbeinglin ked .to hellcranks 21 pivotally supported in the drumhead 6. Thev longer harms-of these i be'l l- .whichissdrivenbya pulley 1'8. Toeachec- L I cranks-are forked :tostraddle the shafts 12 1 of the reciprocating ieazehdevices .5 between the shaft-collars 23., :as indicated in Figs. 1 and 2. Since the cloth (not shown) on which a-nap has to be raised is drawn across thewteazel-drum at right angles to the axis sinuously.

of the latterpthe teeth 4 of the card-clothing of the rotaryteazels 4 are operating in planes crossing the axisof rotation of these teazels at rightangles. The teeth 5 of the card-clothing of the rotatable reciprocating teazel-devices 5 musthowever be arranged to meet theconditions arising from the combined reciprocating and rotary motions of these devices. The path described by these teeth will therefore be shaped'more or less 5 Any card-clothing with teeth adapted for raising a nap on woolen goods, etc., may be employed, provided their teeth are properly directed. To aid the cloth' in retaining its true course of travel notwithstanding the lateral action of the reciprocating teazel-devices 5 it is advisable 'tolet the teeth 5 of one group of said teazel-devices 'pointin one direction and the teeth; of the other group in the opposite direction, as

will be apparent from comparing. Fig 1 with Figs. 4 and6. r V

- The operation of my raising-gig is as follows:After the teazel-drum 3 and with it the rotary teazels 4 and the reciprocating teazel-devices 5,,alternately arranged therein, have been set in rotation, the wheel 9, 1O

' and the double-eccentric 14 will be set in motion. In passing the cloth the teeth 4 of the rotary teazels 4 will pick only the weft threads. thereof, which action represents the longitudinal teazeling, because carried out lengthwise of said cloth. This picking of the weft-threads by the teeth 4' can' at the present state of technics be regulated to an extremely fine degree of exactness.- To let the warp-threads undergo a ilar eazeling action by the teeth 5 of the reciprocating teazel-devices 5, the cardclothing of the latter is selected with a View to 'letlithe teeth thereof, on passing trarisversally or crosswise over the cloth, push the 1 hair or fibers of the warp-threads out of their path, crossing that of the teeth 5, into thepath of the teeth 4 of the rotary teazels 4 and thus enable the latter to engage with and exert a teazeling action upon said hair or fibers also. In this peculiar manner it is made possible for the teeth of the rotary teazels 4 to exert a teazeling action upon the weft-threads as well as upon the warpthreads. The work performedby the teeth 5 of the reciprocating teazel-devices 5 to bring aboutthis result represents'the trans verse teazeling, because carried out transversally or crosswise on said cloth. It isof course necessary to arm the tea'Zel-devices 5 with teeth 5vsufficiently sharpto pick'and teazel the warp-threads directly. 7

Instead of employing eccentrics and bell cranks for reciprocating the teazel-devices 5 a cam 24 may be used, the periphery of which being provided with a sinuously shaped groove 25 adapted to receive guidepins 26 which are rotatablymounted-upon the shaft 12 of the reciprocated teazel-deof course possible to employ stationary eccentrics and cams for reciprocating the teazel-dev1ces5 or to reduce their rotary mo-v tion to a very limited degree. 7 Since the teazeling action of the 'reciprocating'teazel devices 5, depends on the speed of saideccentries,- oreof said cam, the pulley18 might be replaced by a step-pulley, or braking-devices might'be employed instead. Ina similar manner the circumferential velocity of the rotary-teazels 4 and that of the reciprocating teazel-devices 5 may be regulated.

Figs. 8 to -12 showanother modification of my invention, wherein the rotatable reciprocatingteazel-devices 50f Figs. 1 to 7 incluslve are replaced by reciprocating rodshaped teazel-devices 34- .The'same means employed for reciprocating the teazel-de-.

vices 5 maybe used for actuating these rodshaped teazel-devlces steadied by tail-rods 35 gulded 1n the drum-head 7. Therotary teazels 4 of'this" modification may be'rotated by any ofthe means suitable forthis purpose and already described in connection with Figs. 1 and 4. These reciprocat ing teazel-rods are arranged in two sets like i the cylindrical reciprocating tea'zel-devices,

in Figs. 1 and 4' and are, like these, provided with card-clothing of which the-teeth 34 of the one set are arranged in opposit1on to the teeth of the other set, as will be apparent on comparingvFig's. 8 and 11. The reciprocating teazel-devicestransfer during their back-stroke any fibrous material gathered on their working-stroke to the cloth from which it is removed by the rotary teazels to be finally carried off by a clean ing-device (not shown) arranged beneath said teazel-drum.
